FIFTH-WHEEL.

SPECIFICATION forming part of Letters Patent No. 294,915, dated March 11, 1884:.

' Application filed September 6, 1883. (No model.)

To all whom it may concern Be it known that I, MICHAEL J. ROGERS, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Fifth- Wheels for Vehicles, of which the followingis a specification.

My invention relates to that class of fifthwheels whose upper member is provided with a flange to protect the lower portion.

Myimprovement consists in the construction hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective View of afifth-wheel embodying my improvement, and of accessory parts. Fig. 2 is an inverted view of the same. Fig. 3 shows the members of my fifth-wheel detached. Fig. at is a transverse section of the two members in position.

A may represent any suitable head-block, and B O D E may respectively represent portions of any suitable axle-bed, axle, perch, and spring. The king-bolt F may, if desired, pass in the usual manner through a hole, 9*, in the upper member of the fifth-wheel, and through the head-block and the lower half of the spring, but is preferably formed (like the king-bolt in Patent No. 283,139) with a dovetail head, which head occupies a correspondingly-formed socket, 9, formed in the under side of the cross bar G, that, being integrally cast with, unites diametrically the remote extremities of a semiannular bar, H, having a downwardly-projecting peripheral flange or lip, h. Perforated tongues g, which extend rearward from the bar G, receive bolts I, by which the casting GggHh is secured'to the perch. Lugs g, projecting from the rear and front of the socket, have perforations g, to receive the ends of the clip which secures the spring to the headblock. The portion H of the said. casting is similarly perforated at t for bolts I, which fasten it to the head-block, the latter being received between project-ions h on the portion or bar H.

The casting GggHh constitutes the upper member of my fifth-wheel. The lower member of the fifth-wheel consists, preferably, of

is'fastened to the axle and axle-bed. The top of each bar J J has a concentric groove or channel. j, to constitute a receptacle for oil or other lubricant.

In addition to the above-described features, I usually brace the upper member of my fifthwheel by the means following: A lug, K, that projects from the concave edge of the upper member of the fifth-wheel at the mid-length thereof, is perforated for a bolt, L, that fastens a brace, M, which, extending rearward, embraces the kin g-bolt F, whence, still extending rearward, but in a bifurcated form, N N, it is secured to the perch by bolts L L. A shoulder, in, upon the brace lVI, coming in contact with the lip h of the member H, assists in the support of said member. WVhere used with a single perch, the brace is carried rearward without branching.

The upper member of the fifth-wheel is preferably of malleable, and the lower of forged, iron or of cast-steel.

I claim herein as new and of my in vention- The article-of manufacture herein described,- which consists in an upper member for fifthwheels, having its semi-annular bar H formed in one piece with its cross-bar G, the annular bar having a downw'ardly-projecting peripheral lip,'a brace-bolt lug, K, projections h, to receive a head-block, and head-block boltholes t between the projections, and the crossbar being located parallel with and beneaththe head-block, and having rearwardly-extending tongues 9', formed with perch-bolt holes, the central king-bolt-head socket g, king-bolt hole and lugs 9, having holes 9', to receive the ends of the spring-clip, as set forth.

In testimony of which invention I hereunto set my hand.

MICHAEL J. ROGERS.
